An Analysis of Scope Economies and Specialisation Efficiencies Among Thai Shrimp and Rice Smallholders AgEcon
Mekhora, Thamrong; Fleming, Euan M..
Smallholders increasingly combine shrimp culture with the more traditional rice enterprise in regions of Thailand suitable for raising shrimps. They can exploit cost complementarities in production by combining activities in these enterprises within their farming systems. At the same time, it makes them more susceptible to on-farm negative externalities between rice and shrimp production, in both directions, causing scope diseconomies. A stochastic input distance model is estimated using data on shrimp and rice production by 52 smallholder households. Results from the estimated model are used to establish whether scope economies or diseconomies exist and whether specialisation in either shrimp or rice production significantly influences technical...

An Assessment of the Impact of Strategic Alliances in Food Processing on the Technical Efficiency of Housewives Groups in Thailand AgEcon
Nonthakot, Phanin; Fleming, Euan M.; Villano, Renato A..
The cottage food processing industry in Thailand comprises mainly small-scale enterprises such as the ‘housewives groups’ that consist of a number of housewives who combine their food processing activities in a particular district or village. The effects of various factors on the performance of these housewives groups is assessed using survey data to estimate a stochastic input distance model. Our results show that membership of vertical strategic alliances at a high level is associated with higher levels of technical efficiency. Other factors positively influencing technical efficiency within these groups are the level of experience of group members, the ratio of workers to total members, government support, the community base of the group as opposed to...

Animal Efficiency in an Intensive Beef Production System AgEcon
Fleming, Euan M.; Fleming, Pauline; Rodgers, Heidi; Griffith, Garry R.; Johnston, David.
A stochastic input distance function is estimated to analyse the efficiency with which physical characteristics of individual lot-fed beef cattle in Australia are combined with conventional inputs to produce a final product possessing defined quality attributes. High mean technical efficiency estimates are reported for all animals and by breed. All partial output elasticities with respect to inputs are of expected sign. Of four outputs included in the analysis, carcass weight and moisture retention in meat after cooking have highly significant coefficients of expected sign, but two meat quality variables have coefficients of unexpected sign indicating that they decline as inputs increase. Some evidence is detected of scope economies between moisture...

Cost Efficiency and Scope Economies of Crop and Livestock Farms in Missouri AgEcon
Wu, Shunxiang; Prato, Anthony A..
This study investigates productive efficiency for a sample of Missouri crop-only (specialized) and integrated crop-livestock (diversified) farms using a cost frontier approach. Results suggest that significant cost inefficiency exists among sample farms. Lower cost efficiency in both types of farms was attributed to improper scale of operations and mis-allocation of inputs. On average, diversified farms were as technically and scale efficient as specialized farms. Lower allocative efficiency diluted gains in technical efficiency and resulted in greater cost inefficiency for diversified farms than for specialized farms. Technical efficiency was independent of farm size, whereas allocative, scale, and scope efficiencies were not.

Economies of Scope in the Management of Mulitple Species Fisheries AgEcon
Singh, Rajesh; Weninger, Quinn.
This paper considers the problem of multiple-species fishery management when targeting individual species is costly and at-sea discards of fish by fishermen are unobserved by the regulator. A dynamic model is developed to balance the ecological interdependencies among multiple fish species, and the technological interdependence which captures costly targeting. Stock conditions, ecosystem interaction, technological specification, and relative prices under which at sea discards are acute are identified. Three regulatory regimes, species-specific harvest quotas, landing taxes, and revenue quotas, are contrasted against a hypothetical sole owner problem. An optimal plan under any of these regimes precludes discarding. For both very low and very high degrees of...

Estimation of a Multi-Input Multi-Output Model of Lot-Fed Beef Cattle in Australia AgEcon
Fleming, Pauline; Fleming, Euan M.; Griffith, Garry R.; Johnston, David.
Most analyses of technical efficiency and productivity focus on the activities of firms or institutions using inputs to produce outputs. In this paper, we report the results of an efficiency analysis that is couched in a different context. We analyse the efficiency with which physical characteristics of individual lot-fed Australian beef cattle are combined with conventional inputs to produce a final product with several attributes that consumers value. Data on 214 animals across seven breeds were used to estimate a stochastic input distance function with multiple inputs and multiple outputs. Estimates were obtained after controlling for differences between breeds, seasons and sex. Because of variations in feeding regimes for different markets, the data...

Evidence of Scope Economies in the Australian Wheat-Sheep Zone AgEcon
Fleming, Euan M.; Villano, Renato A.; Fleming, Pauline.
Scope economies can be used in studies of farming systems to provide a measure of synergies between different farm enterprises and between activities within farm enterprises. In this paper, they are reported for farms in a benchmarking group in the Wheat-Sheep Zone in New South Wales, Australia, by estimating a stochastic input distance function and calculating an ‘economies of scope parameter’. Evidence is presented of scope economies between sheep and beef enterprises, sheep and crop enterprises, and beef and crop enterprises.

Modelling Synergies and Scope Economies between Farm Enterprises and Ecosystem Outputs in the Agricultural Sector in England and Wales AgEcon
Fleming, Euan M.; Hadley, David; Holloway, Garth J..
Interest has been growing in the nature of synergies in agroecosystems, prompted in part by growing concerns about the effects of environmental degradation on agricultural productivity and interrelations between agricultural outputs and ecosystem outputs. Most productivity analyses focus on technology, technical inefficiency and scale effects on productivity; yet scope economies derived from synergies can also have substantial effects that are likely to increase in the future. Scope economies take on special importance when farms diversify to halt declining biodiversity and other forms of environmental degradation. We present results of an empirical case study based on panel data on farms in England and Wales. A stochastic input distance function is...

OFF-FARM INCOME, TECHNOLOGY ADOPTION, AND FARM ECONOMIC PERFORMANCE AgEcon
Fernandez-Cornejo, Jorge; Mishra, Ashok K.; Nehring, Richard F.; Hendricks, Chad; Southern, Malaya; Gregory, Alexandra.
The economic well-being of most U.S. farm households depends on income from both onfarm and off-farm activities. Consequently, for many farm households, economic decisions (including technology adoption and other production decisions) are likely to be shaped by the allocation of managerial time among such activities. While time allocation decisions are usually not measured directly, we observe the outcomes of such decisions, such as onfarm and off-farm income. This report finds that a farm operator’s off-farm employment and off-farm income vary inversely with the size of the farm. Operators of smaller farm operations improve their economic performance by compensating for the scale disadvantages of their farm business with more off-farm involvement....

What Does Initial Farm Size Imply About Growth and Diversification? AgEcon
Melhim, Almuhanad; O'Donoghue, Erik J.; Shumway, C. Richard.
Recent consolidation in agriculture has shifted production toward fewer but larger farms, reshaping business relationships between farmers, processors, input suppliers, and local communities. We analyze growth and diversification of U.S. corn, wheat, apple, and beef farms by examining longitudinal changes in 10 size cohorts through three successive censuses. We fail to reject Gibrat’s law in apple and wheat industries and the mean reversion hypothesis in beef and corn industries. Apple and wheat farms diversify over time. The findings suggest that scale economies diminish for large farms across all four industries and scope economies dominate scale economies for large apple and wheat farms.
